Description

The TU834 MTU supports up to 8 I/O channels and 2+2 process voltage connections. Each channel features two I/O connections and one ZP connection. Input signals are connected via individual shunt sticks (model TY801). The MTU can handle a maximum rated voltage of 50 V and a maximum rated current of 2 A per channel.

This unit distributes the ModuleBus signal to the next MTU in the system, generating the correct address for connected I/O modules by shifting the outgoing position signals downstream.

The TU834 MTU is designed for easy mounting on a standard DIN rail. It includes a mechanical latch that securely locks the unit to the rail for stable installation.
